Web 3.0 is something called the Semantic Web, a term coined by Tim Berners-Lee, the man who invented the (first) World Wide Web.
In essence, the Semantic Web is a place where machines can read Web pages much as we humans read them, a place where search engines and software agents can better troll the Net and find what we're looking for.
"It's a set of standards that turns the Web into one big database," says Nova Spivack, CEO of Radar Networks, one of the leading voices of this new-age Internet.
But some are skeptical about whether the Semantic Web—or at least, Berners-Lee's view of it—will actually take hold.
They point to other technologies capable of reinventing the online world as we know it, from 3D virtual worlds to Web-connected bathroom mirrors.
Web 3.0 could mean many things, and for Netheads, every single one is a breathtaking proposition.
